PT-0-3PSI-01, PT-0-5PSI-01, PT-0-10PSI-01, PT-0-50PSI-01, PT-0-100PSI-01, PT-0-300PSI-01,
PT-0-500PSI-01, PT-0-1000PSI-01, PT-0-3000PSI-01, and PT-0-5000PSI-01 Pressure Transducers
WARNING – Maretron pressure transducers are not approved for use with gasoline. If you wish to
use the FPM100 to monitor pressures or levels of gasoline, you must obtain a pressure transducer
that is approved for use with gasoline.
Instructions
Please follow these instructions to connect any of the PT-0-3PSI-01, PT-0-5PSI-01, PT-0-10PSI-01, PT-0-50PSI01, PT-0-100PSI-01, PT-0-300PSI-01, PT-0-500PSI-01, PT-0-1000PSI-01, PT-0-3000PSI-01, or PT-0-5000PSI01 pressure transducers to the NMEA 2000® network via a Maretron FPM100 Fluid Pressure Module. The wiring
diagram appears in Figure 1 below. The diagram shows a connection to channel #0, but connections to other
channels are similar.
1. Please refer to the FPM100 User’s Guide for detailed information on selecting a mounting location for the
pressure transducer.
2. All Maretron pressure transducer assemblies are equipped with a ¼” NPT male threaded fitting. Install the
pressure transducer to a ¼” NPT female fitting on the system or tank to be monitored with a maximum
torque of 150 in-lbs (16.95 Nm). If you are monitoring a system where pressure spikes or transients will
occur, or where the pressure will exceed the maximum pressure rating of the pressure transducer, install
a Pressure Snubber (PT-SNUB-01) onto the system being monitored first, then install the pressure
transducer to the female port on the pressure snubber.
3. Connect the two wires of the pressure transducer to a free pressure monitoring channel. Connect the red
wire from the pressure transducer to the positive (+) terminal of the channel, and connect the white wire
from the pressure transducer to the negative (-) terminal of the channel. The example in Figure 1 shows
the pressure transducer connected to switch channel 0 with the red wire connected to “P0+”, and the
white wire connected to “P0-”. Pressure transducers of “Gauge” type have a small plastic vent tube in the
connecting cable. Care must be taken not to kink or block this tube or allow it to be exposed to
moisture, or pressure readings will be inaccurate.
4. Use a Maretron DSM250 display (firmware 1.4.7 or higher), the DSM250 viewing function of the Maretron
N2KAnalyzer software, or other Maretron display product capable of configuring the FPM100 to configure
the connected channel. Please refer to the FPM100 User’s Manual for configuration details.

5. Supply Power to the NMEA 2000 network and verify that the pressure channel indicates a valid pressure
reading.
